ears-1 SODERTELJE, SVEDEN, ASSIGNOR TO CHURN.

Application led June'21, 1&21. Serial No.

To all Le/wm. t may concern.'

Be it known Vthat I, JOHANNES VALnnzaan lilR'rnri Rissen@ subject of the ling of Sweden, residing at Saltsjogatan 7, Sodertelje, Sweden, have invented certain new and useful Improvements in Chur-ns, oi"A which the following is a specification.

@wing to the tact that cream separators for hand power nowadays are more `generally driven by meansci3 small electric inotors, the desire has arisen to effect the butter making in the same easy manner. For the said purpose the motor used tor the driving; of the cream separator would, ot course, be the most convenient. This, however. is not possible without. very extensive arrangehments, due to the Vfact, Vthat the churns put on the market are not adapted to actuation by an ordinary high-speed motor. according to this invention the churns are arranged, that the separator and churns may be driven by a motor common to the same.

In theaecompanying drawings Fig. 1 is a side view and Fig. 2 a plan view ot a separator and a churn mounted on the saine ame and driven by the saine motor. Fig. 3 shows Vthe gearinn'ot the churn.

The separator 1 is mounted in the ordinary manner on the one end of a base plate 2, the other end of which carries an electric motor 3 of a of the separator. As a rule the said Amotor is quite sutlicient for driving a churn, corresponding` to the size of the separator, owing' to the tact that the amount of power for churning is not greater than the'amount of lower for skimming, especially if churning is effected twice a week, as generally is the case. The churning` operation may, e-vidently, not be effected at the same time as the separating' operationl The said separator 1 is driven in the well known manner by the motor 3 by means of a rope l and ropeV 6 provided on the shafto'f pulleys and 45 the motor and the worm wheel shaft of the separator respectively.. VlWhen churning is to be effected, the milk tank 7, belonging to the separator, is removed and on its place, consequently on the milk tank bracket 8, a special gearing` made for the purpose and adapted to drive a churn 9` is mounted. VThe churn 9 is rotatably mounted on a spindle 10 fixed in the betteln of a casing;

size suitable for the driving,-`

11, containing' the said gearing. The rope pullejI 5 of the motor is by means oilt a special rope 12 connected with a rope pulley 13 i'ixed to a shaft let belonging to the said gearing. The gear shown in Fig'. 3 is adapted to a vchurn of the A.general tvne and consisting of a vessel et Vsheet metal and provided inside with a stationary stirrer 9X on spindle 10. The saidgearing comprises a worm 15 provided on the shaft 141 and a worin wheel 16. rotatably mounted on the spindle 10 and connected with the churn 9 by a Vconveyor pin 17. rlthe dimensions et the said worm and wormwheel are so adapted that at a speed of the churn ot about ZOO turns per minute the number shaft 14 about the same as the nuinlier et turns ot the motor` which generally is 1500 to 2000 per minute. Consequently. uthe number turns ot the shaft 1a ought to be about 1000 per minute. The rope pulley 13 or' the shaft 14 has such a diameter. that the rope pulley 5 of the motor may be used :for driving the separator as well as the churn without changinaa the position et the inotor.

rlhe casing; 11 of the gearing is'provided at its lower side with alud 18, which embraces an arm 19. extending from the bracket 8 and located in the central vertical plane of the separator. The said luglr 1S is provided with a set screw 2O. by means of which the casing); 11 is jammed to the said arm 19. v@wing to the .said arrangement the driving: rope 12 may be tightenedlr when necessary. by moving the casina' 11 outward on the arm 19, so that the distance between the rope pulleys 5 and 13 is increased.

It a churn oit a type different trom the one shown in the drawings is used, the details of the `gearing' evidently are adapted to the same. Y l i The advantages of the device described abovebesides other ones, consist in that the same motorrand rope pulley may be used ior the driving et the separator and churn,A that the motor may remain on its ordinary place on the base plate of the separator during' the'churning` operation, and that the driving rope extended trom the motor to the churn is not a hindrance and may easily be tightened, when necessary.

l claim:

ln a device of the character described L of turns of the Y holder for a milk tank when used as a eentiifuge, churning means, a. churn supporting and driving means including a casing detaeiiably secured upon said holder.` a Shaft mounted in said easing; and Carrying the churn, diivim gearing in sii-id casing and .i n n operative to aetuete said churning means, and actuating means or said centrifuge operatively connected to said driving' gem ing' for opei'ating the same.

in testimony whereof I have affixed my signal-nie in peseneeV of two Witnesses.
